identifyNormPars {bootComb}R Documentation

Determine the parameters of the best-fit normal / Gaussian distribution for a given confidence interval.

Description

Finds the best-fit normal distribution parameters for a given confidence interval and returns the mean and sd parameters.

Usage

identifyNormPars(qLow, qUpp, alpha = 0.05, initPars = c(0, 1), maxiter = 1000)

Arguments

qLow

The observed lower quantile.

qUpp

The observed upper quantile.

alpha

The confidence level; i.e. the desired coverage is 1-alpha. Defaults to 0.05.

initPars

A vector of length 2 giving the initial parameter values to start the optimisation; defaults to c(50,50).

maxiter

Maximum number of iterations for optim. Defaults to 1e3. Set to higher values if convergence problems are reported.

Value

A vector of length 2 giving the 2 parameters mean and sd for use with rnorm/dnorm/pnorm/qnorm.
